An impressive church with a lot of great art on display inside. A highlight for me were the amazing Ghirlandaio frescoes. There are more frescoes outside in the attractive cloisters. It's quite a large site with lots to see. It was very quiet and peaceful when we were. We lingered longer than we thought we would. It doesn't seem to be one of the most visited sights in Florence (well there is a lot of competition) but I think it will reward all who venture in there.
